Understanding CNC Machine Safety

CNC router safety is not to be ignored. CNC routers and plasma tables are highly advanced and powerful machines that allow us to perform precise work on an accelerated timeline. But they’re so high-powered and efficient they can also be dangerous if not used properly.

Safety should always come first at home or in the shop. Using your machine safely will also extend its life and produce a higher-quality product. Proper training, regular maintenance, and adherence to manufacturer guidelines are essential for safe CNC machine operation. Although we always recommend consulting with a safety advisor for your shop needs, here are some key best practices to utilize in your CNC work to ensure a safe and effective result.

KNOW YOUR MACHINE WITH PROPER TRAINING

The first and most important rule of safety in CNC work is understanding how to use your machine to perform your intended task properly. Using a machine you’re not trained to use or simply guessing at specific steps of a particular process can be a dangerous way of doing business. It is likely to result in a low-quality product and added wear and tear on your machine. Proper training is essential to ensure you understand and can operate the machine safely and effectively.

Before you dive in, make sure you understand and have a plan for what you’re doing. If you don’t, don’t be afraid to consult an industry professional or turn to your manual for guidance.

Ensure your safeguards are in place

Most CNC machines have built-in safety mechanisms to protect the machine and the user during work. These typically include curtain guards, contact mats, an emergency stop button, and more. These mechanisms are built into the machine for a reason, and you should make sure they are set up properly before you begin your work.

Understanding and using the control panel is crucial for safety. It allows machinists to manage different operational levels of machinery through a locking key switch. This switch ensures that the right level of access and restrictions are enforced based on the task at hand.

In some cases, it may be necessary for you to install safety mats and guards as determined for your and your employee’s safety.

PRACTICE SHOP SAFETY WITH PERSONAL PROTECTIVE EQUIPMENT

If you’ve spent enough time in the shop whether at home or professionally, you’re no doubt aware of the many basic safety guidelines inherent in such a setting. These include:

• Wearing eye and ear protection
• Wearing closed-toe shoes or boots
• Containing long hair when near the machine
• Standing clear of the machine during operation
• Powering down and cleaning the machine after each use
• Avoiding loose clothing to prevent entanglement in machinery

Following these simple guidelines already puts you on a positive track to promoting proper safety in all other work areas. As soon as you start slacking in these easier areas, it’s easy to let yourself slide into different areas, so ensure the simple safety tasks are taken care of.

Dont modify your machine

It may be tempting to make unauthorized alterations to your machine to make it perform a certain way, but doing so can have dangerous effects on its operation and can also damage its components. Accessories and additional options are available for many CNC machines that will help you safely achieve your desired result.

Unauthorized modifications can lead to faulty wiring, which poses severe electrical hazards such as electric shocks and fires, endangering the operator and the overall workspace.

Knowing your machine also means working within its specified capabilities and not trying to make it perform tasks it’s not designed to perform.

Again, many machines are engineered to operate in a specific way, and any alteration can have a ripple effect.

DOUBLE-CHECK BEFORE OPERATING CNC MACHINES

There are several things you should confirm before completing a cut, including:

• That the machine isn’t running
• That the tools are set correctly
• That the correct tool data is set
• That the spindle and machine direction are properly set
• The cutting tools are sharp, and none of them are cracked or chipped
• That the hold-down method is properly installed and functioning

You should also make sure the bit path is clear of obstructions. Failure to do so could result in the obstruction becoming part of your project or shooting in the direction of you or someone else in the shop.

OTHER SAFETY TIPS FOR CUTTING TOOLS

Other essential safety tips to practice on an ongoing basis center around keeping the machine clean and well-maintained before and after every use. This will extend the life of your machine and will also produce higher-quality work consistently.

Additionally, be aware of the chemical hazards associated with cutting fluids and coolants. Direct exposure to these substances without appropriate protective equipment can lead to potential health complications.

What is on-demand rapid tooling and low-volume molding?

From the dashboard of your car to the lid of your coffee cup, billions upon billions of everyday objects are brought into the world by molding, a process in which a hollow container is filled with a molten material to produce large numbers of a single object.

Since molding allows multiple copies of a single product to be produced, it is usually associated with mass manufacturing. However, with new digital manufacturing technologies like additive manufacturing (3D printing) and CNC machining, it is now possible to create a kind of prototype mold in an extremely short space of time. This process is known as rapid tooling.

While molds created via rapid tooling are not usually used for the mass production of objects, they can still be used to produce many copies of a single item. For this reason, low-volume molding — the creation of small quantities of molded products — is often carried out in conjunction with rapid tooling, giving customers a batch of a prototype product rather than just a single copy.

The advantages of rapid prototyping and low-volume molding are numerous. What follows is an overview of some of the key benefits of the two related processes.

Advantages of rapid tooling and low-volume molding

One of the biggest advantages of rapid tooling is right there in the name: speed. Since digital manufacturing technologies like additive manufacturing and CNC machining can be used to create molds in a very short space of time, rapid tooling service providers can offer fast turnarounds on products made with those molds. For businesses, that means getting hold of products faster and getting them to market sooner.

There are also big cost advantages to rapid tooling. Since the bulk of the process involves just a computer and an automated machine like a 3D printer, rapid tooling ends up being far cheaper than traditional toolmaking, with cost savings passed on to the customer. This results in affordable molded products even in low volumes.

Besides time and cost savings, there are other more specific benefits to rapid tooling and low-volume molding, some of which relate to the digital manufacturing processes used to create the molds. Since CAD is used to create the mold, manufacturers can ensure consistency across several molds by simply reusing the same digital file. Digitally creating these tools also allows for easy optimization of cooling channels and other features, and for quick modifications on future molds.

On-demand rapid tooling and low-volume molding is also, for several reasons, an effective precursor to mass manufacturing a product.

For one, rapid tooling can be used to mold products in a range of materials, and since the molds can be produced extremely quickly, manufacturers can make small quantities of a product in different materials and finishes, helping the customer decide on the ideal configuration for their product.

Secondly, such prototype molds are useful for bridge production, when, for example, a customer needs to get the first batch of products to market before regular tooling has been completed. Low-volume molding of a product can also help a customer iron out any previously unnoticed flaws in a product before moving on to mass production.

Dendrobiums are cool as well as warm loving orchid and is sympodial in habit and epiphytes in habitat. They are native to South East Asia and South Asia but are also found in other parts of the world.

Dendrobiums are commercially cultivated both for potted flowering plants and cut flowers. This genus have both evergreen and deciduous types and is characterized by flower spike emerging from the new growth and old canes respectively.

The general cultivation technique is similar in all orchids (preferred temperature and high humidity). It can be cultivated in a pot or can be planted in the ground with modified media with good drainage. Potted plants or plants planted in the modified media in the ground can be kept under shade net to prevent injury by direct sun light.

Dendrobiums can be propagated by seeds, division, cuttings or separation of adventitious growths (kiekies) and micro propagation. The most common being division or cuttings at domestic scale and micro propagation for commercial scale. The popular media used for growing Dendrobiums are a mixture of brick bits, charcoals, coconut
husks, bark chips or stones.

The most important thing is the media needs to be porous, aerated, well drained and slightly acidic (pH 5.0). Prior to use of the media, it is recommended to fumigate with Sylvox (Hydrogen peroxide with nano silver) at 2-3ml/L. After transplanting, irrigation should be given but the media needs to dry between the intervals; irrigation needs to be done more frequently during the summer months.

Dendrobium performs well with 20:10:10 NPK at 0.1% (1g/L water) foliar application at fortnightly interval during the vegetative growth phase in the first year. However, second year onwards nutrition application is based on growth, flower bud initiation or flowering stage.
